Description
This report presents the overview of the runs related to Ad-hoc Video Search (AVS) and Activities in Extended Video (ActEV) tasks on behalf of the ITI-CERTH team. Our participation in the AVS task is based on a cross-modal deep network architecture utilizing several textual and visual features. As part of the retrieval stage, a dual-softmax approach is utilized to revise the calculated text-video
similarities. For the ActEV task, we adapt our framework to fit the new dataset and overcome the challenges of detecting and recognizing activities in a multi-label manner while experimenting with two separate activity classifiers.
